Acceleration of graphics for remote display using redirection of rendering and compression

Abstract

A system and method are disclosed for improving the remote display of graphics images by the redirection of rendering and the optional use of image data compression. Instead of sending graphics commands over a network and rendering on a remote computer system, graphics commands may be automatically redirected by modified OpenGL functions to local graphics devices without explicit involvement by the graphics application. The modifications to a set of the OpenGL functions on the local system are transparent in the normal mode of rendering and displaying locally. After an image is rendered locally, it may be read back and sent across the network. A standard X Server on the remote system may be sufficient to support this methodology. An X Extension for data decompression on the remote system, however, may allow for more efficient image transmission through the use of image data compression.
